Officers said they had quizzed 100 people and searched 500 apartments.
British ambassador to Portugal, John Buck, said police were doing everything they could to find the girl, following some criticism of the investigation.
Officers have not released any photofit or artist's impression of the suspected abductor.
But they have, apparently, shown a sketch like this to residents in Praia da Luz.
While I think the Portugese police should not be hindered in their investigations, I think it is totally ridiculous to issue a photo fit picture like that above. I could be flippant and suggest that a person with features like that should not be too hard to spot. The police say they won't release an image of the man in case he takes fright and flees the country - in all probability he is no longer in the country and so, in my opinion, a proper description/photo fit should be released in countries where he may take refuge. Whatever happened to 'wanted posters' being placed in public places such as airports and train stations so that people could possibly identify criminals? Oh sorry I forgot - that's a breach of the criminal's civil/human rights - never mind how much they breach our civil/human rights.
